Observation - Secret symbol ladybird - UK and Ireland. Description: This tiny ladybird was noticed only while I was having a look at a bit of bone, might be a vertebra,

This tiny ladybird was noticed only while I was having a look at a bit of bone, might be a vertebra, lying on the sandy beach at Lossiemouth.
.
I have no books on ladybirds but checked a variety of on line sources including this site and an article in an issue of British Wildlife (2019, 30, 4, pp167-176). As usual overthinking took over and I couldn't get anywhere near deciding anything! Two Spot? The unusual form of Two Spot? Ten Spot?
.
My friend A came to mind since he knows an enormous amount about wildlife and has the patience of a saint, even with me. Also, he passed on a great pile of BWs to me, including the article referred to above. I sent a photo or two and A fired right back with his diagnosis of Hieroglyphic Ladybird. Then I looked (again!!) at the posts of the species on this site, and realised my fellow WTS volunteer JN had spotted one: https://www.ispotnature.org/communities/uk-and-ireland/view/observation/802737/unknown-ladybird earlier in the year.
.
The BW article has a table stating that this species is decreasing and found (1976 to 2016) in 186 10 km squares, with only 395 records cf Orange 5 000+ and 2 Spot, 16 000+. Coleoptera.org notes its variability and that it is strongly associated with heather. That site shows one image of the species. https://www.coleoptera.org.uk/species/coccinella-hieroglyphica A had recently seen one, not close to heather either.

ID notes: A says so........
